APPARATUS FOR SEPARATING THE FIBERS 0F wIsTnn norns or CRIN VEGETAL AnDTHn LIKE MATERIAL.

Application filed September 30, 1927, Serial No. 223,092,:1116 in the Netherlands March 14, 1927.

The invention relates to a method of untwisting and separating the twisted ropes of crin vgtal or other fibers. i

The crin vgtal, at the place where'it is growing (in the main in North-Africa) is twisted into ropes and dried. After the disentanglement of the rope the fiber retains curled. shape and its elasticitj, and "is used to replace the much more expensive horsehair for upholstery purposes.

The object of the invention is to constitute a machine, by which the twisted ropes may be disentangled in a simple manner quick and free from dust.

It has already been proposed to untwist and tease ropes of this kind by means of. a rotary right angled nozzle, through which the rope is caused to pass. A casing withln which the nozzle is rotating is so shaped as to form a guide for the end of the rope whirled round. by said nozzle so as to direct it against spikes projecting from the inside of said cas- The invention consists in this, that the ropes are fed into a tube shaped part of a fan and are caused to rotate with same in a plane perpendicular to the feeding direction, Further the ropes on passing out of said tube shaped part pass along a set of combs or pins after which the fibers, obtainedin this way, are flung away through the body of the fan and are pressed or sucked away by a current of air.

The apparatus by which according to the i invention the method may be carried into effect, has various features with respect to the fan, the feeding device and the combs or pins along which the ropes are caused to pass.

Preferably the apparatus is, according to the invention, constructed in such a way that two fans with feeding devices mounted adjacent each other are driven by a common motor and the bodies of said fans at the lower side are interconnected by a tube, co1n1nunieating with the delivery tube of a third fan, theblade wheel of which is mounted upon one of the shafts of the first mentioned fans.

On the accompanying drawing a machine according to the invention is illustrated by way of example.

Fig. 1 is a front elevation of the total machine.

provided with holes 21.

Fig. 3 is a cross-section of a fan with feeding device. 1

Figs. 4 and 5 are a bottom-view of the top roll and a top-view of. the lower roll respectively with its surrounding parts.

Inthe drawing 1 is the frame of the new machine, upon which at the left and at the right a fan 2 is mounted, driven by means of shafts 3, 4-. and a belt transmission by anelectire-motor.

Each fan 2 comprises a tube shaped inlet piece 6 for the rope, forming the cover for a casing 7, in which toothed rolls 8, 9 upon shafts 10, 11 are mounted for feeding the rope. The shafts are interconnected by a coupling shaft 12 and are driven from the shaftS by stepped pulleys 13, 1a and a speed reduction worm gear 15. In order to prevent the rope fibers from rotating with the rolls 8, 9, guide plates 16, 17 are arranged corre sponding with the profile of the rolls.

The fan blade wheel 18, attached against a flange of the shaft 3 (I'GSP. 1), comprises a projecting guide canal 19 for the rope to be separated, forming the extension of an axial feed canal 20 for the rope, said canal 20being Further the blade wheel comprises the usual blades 22 for sucking dust and very small fibers out of the casing 7 and the chamber surrounding the end of tubc20.

The rope itself is whirled around along a comb device, constructed as follows.

Thetop of the fan body is provided with a cylindrical socket 23 for guiding a sleeve or comb supporting member 24 (Fig. This sleeve has a flange with ears 25 guided along bolts 26; springs 27, the tension of which may be adjusted, force the sleeve 24 in its lowermost position.

The comb itself is indicatedwith the number 28. Itis connected by means of bolts 29 9 with a covering plate 30, in such a way that it may be turned if necessary after wear. To this end a rod is provided with a hand wheel 31, bearing upon. a bridge piece 32 sup ported by the guide bolts 26 and limiting in this nianner at the same time the lowermost position of the comb supporting member 24; By this construction the comb supporting member 24 may take automatically more or less a position corresponding to the thick ness of the rope, thus promoting the effect.

" angular tube, one arm thereof being concentrio and integral with a rotating shaft which has positioned thereon, a fan blade wheel causing axial suction, an arm of said rotary angular tube perpendicular to first mentioned arm conducts the rope so that the end thereof strikes a comb which is adjustably' positioned on a casing and which encloses the rotating fan blade wheel, angular tube and rope.

2.An apparatus for untwisting, teasing and separating thefibers of twisted ropes of crin ygtal and like material, said ropes being fed thru a nozzle shaped inlet piece thru toothed rolls and into an arm of a. rotary angular tube, one arm thereof being concentric and integral with a rotating shaft which has posltloned thereon a fan blade wheel causing anal suction, an arm of and rotary angular tube perpendicular to first mentioned arm conducts the rope so that the end thereof strikes a comb which is adj nstably positioned on a casing and which encloses the rotating fan blade wheel, angular tube and rope, said casing having a tubular construction at the lower side thereof and being connected to a blower which is mounted on the aforemen tioned rotating shaft.

' '3. Apparatus for untwisting, teasing and separating the fibers of twisted ropes of crin vgtaland like materiahby which the ropes are fed into a rotary angular tube, arranged in a casing andare caused to rotate with same in a plane perpendicular to the feeding direction and to passalong a comb, character ized in that ib'COIlSiSlZS of a fan provided with a fan blade wheel w1th central axial. suct1on, n which an angular tube 15 arranged --as a guide passage for the ropes, projecting with one of its arms from a sidewall of the fan blade wheel and directing with this projecting part. to and communicating with a feeding ease for the material to be treatedand attached to a side cover of the fan blade wheel chamber, and directing with its other arm to the peripheral surface of the fan blade wheel chamber provided with a comb, the

-fan blade wheel chamber at the inside of thetube as well as at the outside thereof being in communication with the feeding case comprising two rolls provided with pins, the shaft of said rolls being mounted perpendicular to the shaft of the fan and that guide members are arranged between said rolls and the inlet opening of the angular tube arranged in the fan blade wheel. in such a way that the rope after passing between the rolls is caused to enter into said angular tube of the fan blade wheel.

4. Apparatus for untwisting, teasing and separating the fibers of twisted ropes of crin vegtal and like material, by which the ropes are fed into a rotary angular tube, arranged in a casing and are caused to rotate with same in a plane perpendicular to the feeding direction and to pass along a comb, characterized in that. it consists of a fan provided with a fan blade wheel with central axial suction, in which an angular tube is arranged as a guide passage for the ropes, projecting with one of its arms from a sidewall of the fan blade wheel and directing with this projecting part to and communicating with a feeding case for the material to be treated and attached to a side cover of the fan blade wheel chamber, and directin with its other arm to the peripheral surlace of the fan blade wheel clnunher, provided with an epen- I o I t mg at the top sale, iljenm'ng cyllmlnell guide for a comb supportingmember slidably mounted therein, and resilient means acting on said supporting member for keeping the comb auton'latically projecting from the inside of the fan blade wheel, chamber, which at the inside of the angular tube as well as at the outside thereof being in communicat-ion with the feeding case.
